Spherically symmetric black holes in Gravity from Entropy and spontaneous emission
Udaykrishna Thattarampilly, Yunlong Zheng, Vishnu Kakkat
We investigate static and dynamical spherically symmetric black hole solutions within the Gravity from Entropy (GfE) framework. We derive and solve the modified vacuum field equati…
Photometric Objects Around Cosmic Webs (PAC). VII. Disentangling Mass and Environment Quenching with the Aid of Galaxy-halo Connection in Simulations
Yun Zheng, Kun Xu, Donghai Zhao +4
Star formation quenching in galaxies is a critical process in galaxy formation. It is widely believed that the quenching process is dominated by the mass of galaxies and/or their e…
Robust detection of hot intragroup medium in optically selected, poor galaxy groups by eROSITA
Dawei Li, Taotao Fang, Chong Ge +7
Over the last several decades, extensive research has been conducted on the baryon cycles within cosmic structures, encompassing a broad mass range from dwarf galaxies to galaxy cl…
PAC.V. The Roles of Mass and Environment in the Quenching of Galaxies
Yun Zheng, Kun Xu, Y. P. Jing +6
The roles that mass and environment play in the galaxy quenching are still under debate. Leveraging the Photometric objects Around Cosmic webs (PAC) method, we analyze the excess s…
The DESI One-Percent survey: constructing galaxy-halo connections for ELGs and LRGs using auto and cross correlations
Hongyu Gao, Y. P. Jing, Shanquan Gui +31
In the current Dark Energy Spectroscopic Instrument (DESI) survey, emission line galaxies (ELGs) and luminous red galaxies (LRGs) are essential for mapping the dark matter distribu…
Measuring the X-ray luminosities of DESI groups from eROSITA Final Equatorial-Depth Survey: I. X-ray luminosity -- halo mass scaling relation
Yunliang Zheng, Xiaohu Yang, Min He +3
We use the eROSITA Final Equatorial-Depth Survey (eFEDS) to measure the rest-frame 0.1-2.4 keV band X-ray luminosities of 600,000 DESI groups using two different algorithms…
eDIG-CHANGES I: Extended Hα Emission from the Extraplanar Diffuse Ionized Gas (eDIG) around CHANG-ES Galaxies
Li-Yuan Lu, Jiang-Tao Li, Carlos J. Vargas +14
The extraplanar diffuse ionized gas (eDIG) represents the cool/warm ionized gas reservoir around galaxies. We present a spatial analysis of H images of 22 nearby edge-on spiral…
Photometric Objects Around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. IV. High Precision Constraints on the Evolution of Stellar-Halo Mass Relation at Redshift
Kun Xu, Y. P. Jing, Yun Zheng +1
Taking advantage of the Photometric objects Around Cosmic webs (PAC) method developed in Paper I, we measure the excess surface density of photometric objects…
Gas dynamics and star formation in NGC 6822
Hye-Jin Park, Se-Heon Oh, Jing Wang +3
We present H I gas kinematics and star formation activities of NGC 6822, a dwarf galaxy located in the Local Group at a distance of ~ 490 kpc. We perform profile decomposition of l…
HI Vertical Structure of Nearby Edge-on Galaxies from CHANG-ES
Yun Zheng, Jing Wang, Judith Irwin +9
We study the vertical distribution of the highly inclined galaxies from the Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES). We explore the feasibility of photometri…
CHANG-ES XXV: HI Imaging of Nearby Edge-on Galaxies -- Data Release 4
Yun Zheng, Jing Wang, Judith Irwin +9
We present the HI distribution of galaxies from the Continuum Halos in Nearby Galaxies - an EVLA Survey (CHANG-ES). Though the observational mode was not optimized for detecting HI…
The Compactness of Galaxy Groups in the Sloan Digital Sky Survey
Yunliang Zheng, Shiyin Shen, Shuai Feng
We use an updated version of the halo-based galaxy group catalog of Yang et al., and take the surface brightness of the galaxy group () based on projected positions an…
Construct the emission line galaxy-host halo connection through auto and cross correlations
Hongyu Gao, Y. P. Jing, Yun Zheng +1
We investigate the [O\,II] emission line galaxy (ELG)-host halo connection via auto and cross correlations, and propose a concise and effective method to populate ELGs in dark matt…
Photometric Objects around Cosmic Webs (PAC) Delineated in a Spectroscopic Survey. I. Methods
Kun Xu, Yun Zheng, Yipeng Jing
We provide a method for estimating the projected density distribution of photometric objects around spectroscopic objects in a redshift survey. This quantity de…
Strong Conformity and Assembly Bias: Towards a Physical Understanding of the Galaxy-Halo Connection in SDSS Clusters
Ying Zu, Yunjia Song, Zhiwei Shao +6
Understanding the physical connection between cluster galaxies and massive haloes is key to mitigating systematic uncertainties in next-generation cluster cosmology. We develop a n…
Compact Groups of Galaxies in Sloan Digital Sky Survey and LAMOST Spectral Survey. II. Dynamical Properties of Isolated and Embedded Groups

Compact groups (CGs) of galaxies appear to be the densest galaxy systems containing a few luminous galaxies in close proximity to each other, which have a typical size of a few ten…
Compact Groups of Galaxies in Sloan Digital Sky Survey and LAMOST Spectral Survey: I. The Catalogs
Yunliang Zheng, Shiyin Shen
A compact group (CG) is a kind of special galaxy system where the galaxy members are separated at the distances of the order of galaxy size. The strong interaction between the gala…
